Cyan Skillfish APUs in Navi 1x fairly than Navi 2x talked about in Linux 5.15.
With desktop graphics playing cards, AMD has been rolling out its RDNA2 structure for a number of months, and plans to launch the primary RDNA3 merchandise subsequent 12 months. On the APU facet, however, the built-in graphics options stay beneath the Vega structure, together with these of the Ryzen 5000 desktop APUs. Nonetheless, the corporate ought to quickly carry the RDNA 2 structure to one of these product, presumably with the subsequent Rembrandt and Van Gogh APUs. However in accordance with an entry on Linux 5.15 mentioning a “Cyan Skillfish” GPU, the corporate would additionally provide chips with an built-in graphics processor RDNA (Navi 1x).
Quite a few checks have confirmed that for devoted graphics playing cards, the RDNA2 structure is considerably extra environment friendly and environment friendly than the RDNA1 structure. Then again, within the case of an APU, it includes a significant downside: the presence of Ray Accelators and bigger die surfaces; logically, these constraints change into harder to handle than with a devoted graphics card. Consequently, AMD would put together each APUs beneath RDNA and RDNA2 structure able to adapting higher to the platforms. Keep in mind that presently, along with devoted graphics playing cards, the SoCs of the PlayStation 5 and Xbox Sequence X / S additionally profit from the RDNA2 graphics structure.

RDNA1 just for entry degree APUs / SoCs?
Regarding RDNA, we will solely make assumptions for the second. The obvious: AMD would reserve this structure for entry-level APUs or SoCs. However the firm might additionally determine to generalize the combination of an built-in graphics resolution to its Ryzen processors. That is the usual at Intel, solely the F fashions being devoid of iGPU. In brief, we are going to see within the coming months what Cyan Skillfish is finally supposed for.
